The purpose of this study was to investigate the protective effects of fucoidan on acute alcohol-induced liver injury in rats. Experimental animals were randomly divided into four groups: (1) a control group, (2) a group fed 25% ethanol, (3) a group fed 25% ethanol and 250 mg/kg BW of fucoidan (25% ethanol+FUCO250), and (4) a group fed 25% ethanol and 500 mg/kg BW of fucoidan (25% ethanol+FUCO500). Each group was fed orally two times per day for 15 days. Liver weights in the 25% ethanol group were increased compared to the control group, while liver weights in the 25% ethanol+FUCO500 group were significantly decreased compared to the 25% ethanol group (p<0.05). Plasma concentrations of triglyceride, cholesterol, and LDL-cholesterol were elevated in the 25% ethanol group; however, these levels in the 25% ethanol+FUCO250 group were significantly decreased compared to the 25% ethanol group (p<0.05). The glutamic-pyruvic transaminase activity of the 25% ethanol+FUCO500 group also was significantly lower than the 25% ethanol group (p<0.05). These results indicate that fucoidan might protect against acute alcohol-induced liver injury. copyright © 2014 The Korean Society of Food Science and Technology. Source

We examined whether α-linolenic acid (ALA) alters total-cholesterol and haemostatic factors and the relationship between such alterations and lipoprotein-associated phospholipase A2 (Lp-PLA2). Eighty-six non-diabetic, borderline-to-moderate hypercholesterolaemic human subjects were divided into two groups: ALA group and placebo group. After 8 weeks of treatment, the ALA group exhibited significant increases in plasma ALA, and reductions in total- and LDL-cholesterol. The ALA group showed significantly greater reductions in total- and LDL-cholesterol, ox-LDL, apo B and Lp-PLA2 activity and greater increases in plasma ALA, activated partial thromboplastin time (aPTT) and collagen-epinephrine (C-EPI) closure time (CT) than the placebo after adjusting for baseline levels. Independent and significant correlations between changes in C-EPI CT and plasma ALA, and between changes in aPTT and Lp-PLA2, were observed. In conclusion, ALA supplementation was associated with prolonged C-EPI CT and aPTT and decreased Lp-PLA2, which were mediated by decreasing LDL-cholesterol oxidation, thereby reducing substrate available for Lp-PLA2 (ClinicalTrials.gov: NCT02609295; http://www.clinicaltrials.gov). © 2016 Elsevier Ltd.

Objectives: Since oils and fats can induce metabolic syndrome, leading to cardiovascular and cerebrovascular diseases, the present study was performed to find out whether the plant oils affect the cerebral hemorrhage in stroke-prone spontaneously hypertensive (SHR-SP) rats. Methods: From 47 days of age, male SHR-SP rats were given drinking water containing 1% NaCl to induce hypertension, and simultaneously fed semi-purified diets containing 10% perilla oil, canola oil, or shortening. The onset time of convulsion following cerebral hemorrhage was recorded, and the areas of hemorrhage and infarction were analyzed in the stroke brains. Results: In comparison with 58-day survival of SHR-SP rats during feeding NaCl alone, perilla oil extended the survival time to 68.5 days, whereas canola oil shortened it to 45.7 days. Feeding perilla oil greatly reduced the total volume of cerebral hemorrhage from 17.27% in the control group to 4.53%, while shortening increased the lesions to 21.23%. In a microscopic analysis, perilla oil also markedly decreased the hemorrhagic and infarction lesions to 1/10 of those in control rats, in contrast to an exacerbating effect of shortening. In blood analyses, perilla oil reduced blood total cholesterol and low-density lipoproteins which were increased in SHR-SP, but canola oil further increased them and markedly lowered platelet counts. Discussion: Perilla oil delayed and attenuated cerebral hemorrhage by improving hyperlipidemia in hypertensive stroke animals, in contrast to the aggravating potential of canola oil and shortening. It is suggested that perilla oil should be the first choice oil for improving metabolic syndrome in hypertensive persons at risk of hemorrhagic stroke. © W. S. Maney & Son Ltd 2016 Source

Anti-adipogenic and anti-obesity effects of a green coffee been extract (GCE) from unroasted Coffea canephora Robusta beans were investigated in vitro and in vivo. Insulin-induced adipogenesis in 3T3-L1 preadipocytes was inhibited by 25.6 and 87.9% following treatment with 100 and 500 μg/mL GCE, respectively. Expression of adipogenesis-specific genes was down-regulated. Body weight gains of C57BL/6 mice fed a high-fat diet (HFD) were suppressed in a concentration-dependent manner using GCE (0.3 or 1% in the diet), exhibiting a marked lower gain in 1% GCE-fed mice than in normal diet-fed animals. Decreases in body fat weights and the size of adipocytes were confirmed. GCE supplementation reduced concentrations of blood lipids and leptin, and attenuated hepatic steatosis. GCE inhibits adipogenesis by modulating cell signaling and improves dietary obesity by reducing lipid accumulation and the size of adipocytes. © 2014, The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

A placebo-controlled double-blind ingestion study of a beauty supplement containing rice-derived ceramide was performed. Thirty three subjects who always tended to have rough skin due to dryness participated in the study. Dermatological diagnosis by physicians showed that the supplement significantly improved dryness and itching of the skin. On measurement of water content in the skin, the supplement was shown to significantly increase water content in the skin. On microscopic three-dimensional analysis of the epidermis, the supplement was shown to improve smoothness, exfoliation, and short-term ingestion of the supplement containing rice derived ceramide, which is very effective as skin beautifying food. © The Korean Society of Food Science and Technology.
